Shielded High Current Class D Amplifier Inductor 3R3

This Class D Amplifier Inductor features 3R3 inductance value, engineered as a high-current shielded power inductor adopting flat wire winding technology. The shielded structure effectively reduces electromagnetic interference and avoids mutual disturbance to surrounding circuits. Flat wire design improves current carrying capacity, lowers DC resistance and cuts heat generation during continuous operation. Designed for surface mount assembly, it supports automated SMD production to boost manufacturing efficiency. Widely used in Class D audio amplifiers, switching power supplies and related power conversion equipment.

Product detail

Structural Craftsmanship

Robust Magnetic Shielding: Encapsulated in a heavy-duty shielded core structure that effectively suppresses electromagnetic interference (EMI) and prevents magnetic coupling with adjacent components on dense PCB layouts.

Laser-Marked Clarity: Features a precise, high-contrast "3R3" inductance marking laser-etched onto the top surface for instant identification during assembly and quality control.

Core & Winding Design

Flat Wire Edge-Wound Construction: Wound with high-grade flat copper wire, maximizing the conductor cross-sectional area within a compact footprint. This significantly reduces AC resistance and high-frequency skin effect losses.

Low-Loss High-Frequency Core: Utilizes an advanced high-frequency ferrite material tailored for Class D amplifier filter applications, ensuring minimal core loss, excellent linearity, and pristine audio signal reproduction without distortion.

Termination & Soldering Details

Heavy-Duty Terminal Pins: Designed with wide, robust solder pads/terminals that provide exceptional mechanical stability on the PCB, capable of withstanding high thermal and mechanical stress in demanding audio power environments.

Clean & Uniform Solder Finish: Terminals are tinned to perfection with a bright metallic luster, preventing cold solder joints and ensuring ultra-low contact resistance for maximum current delivery.

Our team will provide a tailored solution for your project.

How do you guarantee product quality, and what is the warranty period?

A: Quality and stability are our top priorities. 100% of our products undergo rigorous testing (including electrical parameters, insulation reliability, and safety screening) before shipment to ensure zero critical defects. We back our products with a solid 90 to 180-day quality warranty, giving you full peace of mind for your supply chain.

What is the typical lead time for samples and bulk orders?

A: Standard lead times are as follows:
Samples: Typically 5 to 10 working days.
Bulk Production: Generally 15 to 30 days, depending on the order volume, product complexity, and raw material inventory.
Note: If your project is urgent, please let us know, and we will do our best to expedite the schedule.

Do you support Low MOQ (Minimum Order Quantity) for new projects?

A: Yes, we fully understand that engineering trials and prototyping require flexibility. We support low MOQ for initial sample runs to help you verify the design before moving forward with volume production.

Are your raw materials compliant with international environmental standards?

A: Yes. We strictly control our supply chain. All key raw materials used in our transformers and inductors comply with international regulatory standards such as RoHS and REACH, ensuring environmental friendliness and smooth customs clearance for your global markets.

Can you provide 2D/3D engineering drawings or data sheets before production?

A: Yes. Once we clarify your technical requirements, our R&D engineering team can provide detailed 2D/3D drawings and preliminary datasheets for your approval to ensure every detail matches your PCB design or system enclosure.

What shipping terms and payment methods do you accept?

A: We offer flexible business terms to accommodate global buyers. We accept various shipping terms including FOB, EXW, and CIF, and support secure payment methods. Please contact our sales team to discuss the most convenient setup for your procurement process.
